2. Champion Power Equipment 75531i – Good for RV’s

Power is of the essence for any RV generator. In any case, an RV generator must handle heavy load such as refrigerators, air conditioning units, microwave, hair dryers to coffee makes. A 2000-watt generator such as WEN 56200i can't provide that much.

Quick S​ummary

  • Quick Touch Panel
  • Ultra-Quiet Operation – 58 dBA
  • Clean Power for Sensitive Electronics
  • Smart Economy Mode
Champion 3100-Watt RV Ready Portable Inverter Generator

As you would expect from any great inverter generator, the Champion Equipment provide clean output supply and will guard you're electronic against overloads.

As I had mentioned earlier, heavy loads usually draw a lot of power when turned on, almost three times the operating power. Often, the huge spike triggers the overload protection in the 2000-watt generator, but the Champion Equipment can handle this demand.


Reliable Power Output

At the heart of the Champion is a 171 cc overhead valve engine that is both reliable and powerful producing a total of 3100 surge watts and 2800 running watts.

With this kind of power, you can run a variety of rather large appliances at home or job sites. The generator is so powerful that it will satiate even the large power tools and even the power-hungriest appliances such as conditioners, and this makes it an ideal choice for RV use as well.

Quiet Operation

With a noise level rated at 58 decibels when measured at 23 feet, the Champion is relatively quiet.

At 58dB, the Champion is a tad louder than a majority of the common lower wattage inverter, and many consumers report that the generator is louder than they expected.

The good news is that at 58dB, the Champion is way quieter than most of the 3000-watt inverter generator in its class.

Ideal for RVs and Camping

Weighing at 80 pounds, alongside wheels and a foldaway handle, this makes the Champion ideal for RVs and camping.

Though the 80 pounds is still a weighty generator, we have seen many portable generators weighing 100-220 pounds or more and stretching the definition of "portable," But at less than 100 pounds, the Champion is quite mobile and easier to use at multiple locations.

Environmental-friendly and Fuel Efficient

Generators can be fuel guzzlers.  Fortunately, with the Champion, you get a CARB-Compliant generator with both reduced emissions and better fuel economy.

Further, this unit features a smart economy mode which promotes quieter operation, while boosting better fuel efficiency.

Easy to Use Control Panel

Sporting a Quick Touch Panel, the Champion is easy to use as it allows you to access all your controls in a single spot.

Portable Inverter Generator Buying Guide

This article aims to ensure that you are happy with your purchase. For this to happen the value, an invertible generator offers must exceed or at the very least correspond with the price you pay for it.

While you can count the money, you can never count value. The good news is that you can get a feel for it if you know where to look.

This section is all about getting the value for your money.

Why Should You Choose an Inverter Generator Over a Conventional/Regular Generator?

Both conventional and inverter generators are an awesome source of power. But why would you consider an inverter generator over the regular generator?

Let’s look at some of the benefits of inverter generators over the regular generators.


The issue of noise is one that truly separates these two categories of generators. Inverter generators are often designed from the ground up to be comparatively quiet.

In any case, these generators are fitted with quieter engines, special mufflers, and sound dampening technology to reduce noise to amazingly low levels.

The maximum noise levels that you can get with an inverter generator is 60 decibels, and to give you a reference for this noise, 60dB is similar to the conversations in an office environment. So, pretty quiet.

Fuel Efficiency

Given that a majority of the inverter generators are small and compact, they have limited fuel tanks translating to lower consumption.

An inverter fuel efficiency can translate to saving as much as 40%, and this will save your money and help to reduce exhaust emissions.

Clean Output

Inverter generators use a rectifier to convert the AC power to DC and capacitors to smooth the power to a certain degree.

With an inverter generator, the output is well regulated, and the inverter system produces consistent power characteristics independent of the engine speed.

The results are much "cleaner" power, i.e., "pure sine waves."

Why is this important?

A majority of the electronics use a sophisticated circuitry of microprocessors; having clean power is of the essence. Given that these microprocessors are extremely sensitive to the quality of electricity using "unclean" electricity can cause the malfunctioning of the devices or even damage to the device.

Size / Weight / Portability

A majority of the inverter generators are generally small, compact and lightweight for electrical generation.

In any case, their dimensions are just about cubic feet, with their weight ranging in between 30 to 50 pounds.

This is to mean the inverter generators are a breeze to transport and store, and they will easily fit in your car, RV or boat when going for a hike.

This is as opposed to the conventional generators, which are bulky, heavy and often requiring substantial metal frame and wheels.

Parallel Operation

Sure, the conventional generator has a greater power output than the inverter generators, the latter can be paired with another identical unit to double up the power capacity.

With the parallel system in place, it means you can use two smaller, lighter generators to provide the same wattage and amperage of one much larger generator, without sacrificing all the benefits of the smaller, lightweight inverter units.

5 Reasons You Would Want to Buy an Inverter Generator

There is always a huge decision to make when buying a generator. If you are stuck at whether to buy a portable inverter generator, here are five scenarios that would make the inverter unit an excellent choice;

1) I Want to Watch TV While Tailgating

At times, you want to be into two places at once-you want to keep the party going and at the same time, want to catch your favorite TV show. If this is you, then you would want to consider an inverter generator.

Inverter generators are convenient, lightweight and compact, and this makes them truly and easily portable.

With these units, you can throw them alongside your TV in your trunk and still have extra space for a cooler.

2) I Can’t Stand Noise

If you’re anything like me, noises drive me crazy, especially when I’m reading my favorite book.


Get an inverter generator that will keep the noises at a bare minimum.

Better yet, you’ll not have your neighbors cursing and frowning on you when you meet next.

3) I Only Need to Charge my Cell Phone

If you are looking forward to charging your phone or any other sensitive electronics such as laptops, computers or tablets, an inverter generator is practically a requirement.

As we mentioned earlier, an inverter generator will provide a much smoother stream of electricity, and greatly reduce the odds of destroying them.

4) I Don’t Want to Kill the Planet

While all the generators use some form of fossil fuel, meaning none of them improves the health of the planet, the inverter generator is much more fuel-efficient.

Beyond fuel efficiency, they don’t produce much electricity, thus giving any of them a smaller environmental footprint, as they only generate as much electricity as is demanded of them.

5) Don’t Want to Refuel After Every 5 Minutes

If you are hoping to turn on the generator on and leave it running for most of the day without worrying about the oil levels, you need an inverter generator.

Though it does not hold as much fuel as the conventional generator, it has an automatic oil shutoff system that will switch off the generator once it detects low oil levels.

How to Select the Right Generator for the Job?

Choosing the right inverter generator has always been a daunting task for many. However, it does not need to be so; in the section below, we shall highlight everything you need to know on selecting the right powerhouse for the job.

1) Determine your power needs: Before making a purchase, ask yourself what you will need to power. Make a list of all the electronics that you intend to power. Is it a TV, phone charging, microwave or the refrigerator? Some of the families might require power for their in-home medical equipment, while others need to ensure they have sufficient power to keep stocked supplies in ice. For the outdoor enthusiasts, make a list of the heating or entertainment appliances or accessories that your family and friends will be using at once.

2) Determine what it takes to start each appliance: Ensure that you can start (not simply run) your appliances.

Understanding Wattage Requirements

There are two basic power requirements that you should consider before making a purchase.

The first one is the starting wattage also known as startup power, max watt or peak power. It's is the amount of wattage required to start an appliance with a motor, and might twice the wattage required to run the appliance.

The second power measurement is the continuous power, which is the amount of wattage required for the operation of your appliances under normal load.

Here is a breakdown of the starting wattage and continuous wattage of some of the popular household and job site equipment.

Starting Wattage

Starting Wattage

Continuous Wattage

Electric Griddle



Desktop Computer w/ 18" LCD Monitor



Inflator Pump



60-watt bulb






Space heater






Washing Machine



Garage Door Opener



Air Conditioner (10,000 BTU's)



Box Fan



CD/DVD Player



Dishwasher - Hot Dry



Inkjet printer



1/6 horsepower electric motor



3) Calculate your total power needs: Calculating your total power needs is a two-part equation. First, you’ll need to add up all the running wattage for all items you wish to power simultaneously, then add that to the highest of the starting wattages. This way, you will know how much power you need to start and run your appliances.

Features That Count

Don’t let rain, snow, or the wind keep you in the dark. Consider these options to ensure you get the best portable inverter generator for your energy needs.

Automatic Start

As its name suggests, an automatic start will automate the entire operation of the generator. For instance, the automatic start will allow you generator to go on once the power goes off-without you having to lift a finger.

This is a great feature, especially if you love traveling a lot or work away from home and can’t always be there in case of an emergency.

Electric Start

The electric start is a push-button alternative to the pull-staring generators. It removes the hassle of starting your generator, though it’s a tad pricier.

Alternative Fuel Capacity

While a majority of the portable generators run on gasoline, there are those that are equipped with a propane tank or natural-gas line for convenience.

Fuel Gauge

A fuel gauge is of the essence, especially during the long blackouts as will appreciate the ability to check at a glance how much fuel is remaining in your portable generator.

Low-Oil Shutoff

Another awesome feature, the low oil shutoff will generally shut down the generator once the oil level dwindles beyond a certain level to prevent engine damage.

Multiple Outlets

Multiple outlets are ideal for spreading the load. Having an inverter generator with at least four outlets is recommendable, though it's only ideal for those in an extreme pinch at home or for when you are away at a campsite.

The Essence of a Transfer Switch

A transfer switch is a feature that safely connects a home standby or portable inverter generator to your circuit panel through a single cable.

While some users often neglect using the transfer switch, skipping it could endanger utility workers, result in the frying of appliances or damage the generator itself.

Therefore, we recommend that you hire a licensed electrician to install the transfer switch. Alternatively, if you are on a budget, you can install an interlock device instead. The latter will cover your service panel’s main cutoff switch, and so when the power pops back, you can’t accidentally put the generator on.

Safety Precautions of Using a Portable Inverter Generator

  • Never connect a generator directly to your home’s wiring
  • Never run a generator indoors or in partly closed areas such as garages
  • Operate the generator only on level surfaces, where it will not be exposed to excessive moisture, dust or corrosive vapors
  • Never overfill the fuel tank
  • Never store a generator for long with gasoline
  • A generator must always be properly grounded
  • Do not overload your generator
  • Always inspect your generator regularly


As you can see, choosing the best invertible generator is not as challenging as it sounds.

Now, you have a list of the top ten invertible generators, plus you are now more knowledgeable on how to pick the right one for your needs.
